We Finally Know How Much It Cost to Train China’s Astonishing DeepSeek Model

gizmodo.com Aj Dellinger 2025-09-21 16:25:37

Remember when DeepSeek briefly shook up the entire artificial intelligence industry by launching its large language model, R1, that was trained for a fraction of the money that OpenAI and other big players were pouring into their models? Thanks to a new paper published by the DeepSeek AI team in the journal Nature, we finally know what it took to train DeepSeek 1: $294,000 and 512 Nvidia H800 chips. The reason it was able to spend less, it seems, is because of the team’s use of trial-and-error-b

Implicit ODE solvers are not universally more robust than explicit ODE solvers

news.ycombinator.com Christopher Rackauckas 2025-09-25 17:41:51

A very common adage in ODE solvers is that if you run into trouble with an explicit method, usually some explicit Runge-Kutta method like RK4, then you should try an implicit method. Implicit methods, because they are doing more work, solving an implicit system via a Newton method having “better” stability, should be the thing you go to on the “hard” problems. This is at least what I heard at first, and then I learned about edge cases. Specifically, you hear people say “but for hyperbolic PDEs

Years of notebooks and a laptop side by side, the Socratic Journal Method blends timeless reflection with modern tools to make journaling a habit that actually works.

Randomly selecting points inside a triangle

news.ycombinator.com Unknown 2025-10-02 15:29:33

If you have a triangle with vertices A, B, and C, how would you generate random points inside the triangle ABC? Barycentric coordinates One idea would be to use barycentric coordinates. Generate random numbers α, β, and γ from the interval [0, 1]. Normalize the points to have sum 1 by dividing each by their sum. Return αA + βB + γC. This generates points inside the triangle, but not uniformly. Accept-reject Another idea is to use an accept-reject method. Draw a rectangle around the triangl

Fix damaged art in hours with AI

In his study, Alex Kachkine, SM ’23, presents a new method he’s developed that involves printing the restoration on a very thin polymer film that can be carefully aligned with a painting and adhered to it or easily removed. As a demonstration, he used the method to repair a highly damaged 15th-century oil painting he owned. First he used traditional techniques to clean the painting and remove any past restoration efforts. Then he scanned the painting, including the many regions where paint had f

LASIK Without Lasers? Scientists May Have Found a Way

gizmodo.com Ed Cara 2025-11-02 12:00:39

What if you could fix your damaged eye without having to shoot a laser at it? Scientists have potentially discovered a novel method of repairing the cornea, similar to LASIK, that wouldn’t require a laser or other invasive surgical tool. Researchers at Occidental College and the University of California, Irvine, created the technique, which aims to temporarily make the cornea malleable. In experiments with rabbit eyeballs, their method appeared to work while also leaving corneal cells alive. Mo

Trump's Nvidia and Intel meddling is a 'scattershot method of crony capitalism': Walter Isaacson

cnbc.com Samantha Subin 2025-11-07 12:35:31

President Donald Trump's dealings with Intel and Nvidia amount to a "scattershot method of crony capitalism," Walter Isaacson said Thursday. "That state capitalism often evolves into crony capitalism, where you have favored companies and industries that pay tribute to the leader, and that is a recipe for not only disaster, but just sort of a corrupt sense of messiness," he told CNBC's "Squawk Box."

Hexatetrahedral Rails

news.ycombinator.com Unknown 2025-12-16 11:56:32

Software is a creative endeavor and a craft. And like any creative endeavor and any craft, it is subject to fashions. About a decade ago, one of those fashions was Hexagonal Rails largely inspired by the DDD book, but also by the original Hexagonal Architecture work by Dr. Cockburn. Some of these applications are now up for their Rails upgrade and an “oil change,” and it’s interesting to see them in the wild and how they get perceived through the lens of the years that have gone by since then.

This Prehistoric Trick Shows How Ice Age People Harvested Teeth for Jewelry

When piecing together the cultural practices of ancient humans, traditional archaeologists rely on clues from artifacts such as tools, bones, and pottery. Experimental archaeologists, however, go a step further—recreating past behaviors to experience how people once lived. That’s precisely what a team of researchers recently did to investigate how Stone Age communities in northeastern Europe extracted animal teeth to produce accessories.

The axion may help clean up the messy business of dark matter

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter. Although the potential for axions to explain dark matter has been around for decades, cosmologists have only recently begun to seriously search for them. Not only might they be able to resolve some issues with older hypotheses about dark matter, but they also offer a dizzying array of promising avenue
